So you own Linux? That's pretty cool - or at least you have some cool people on staff, because they can spout off BASH shell commands that leave you in a daze, and they know the answers to life's tough questions ( ie. the answer is 42). I love these guys because not only do they keep all our systems running, but they will keep you on your toes by spouting out Darth Vader quotes like "I find your lack of faith disturbing", when you question anything that they do.
At the end of the day, Linux and Unix systems are awesome because they run our applications, file systems, high performance computing, and a variety of other tasks that keep our businesses running. However, Linux lacks the powerful directory services database that is found in the world of Microsoft, which has become the defacto standard in enterprises throughout the world. Active Directory touts a robust, scalable, and secure place to centrally store your user identities, passwords, and other server and workstation settings. If you are managing a large number of Linux servers, it can be very costly to support multiple identities and passwords across multiple machines. It can also be a headache to deprovision users off multiple boxes, when access rights are no longer needed, or a employee leaves the work force. This is where Quest Authentication Services can help. It bridges the gap between Linux/Unix/Mac and Active Directory. It simply creates objects in Active Directory to represent your Linux Servers/Workstations, and allows your users to authenticate from their Active Directory accounts, using the corporate password policy setup in Active Directory. It can also centrally manage a whole host of Linux settings like SSH, Sudo, CRON scripts and a lot more, across all your Linux hosts. It makes managing users, passwords and linux settings a cinch.
